1)If you can afford to have your blood tested for everything available, do it quarterly so you have a baseline of your own personal health

2) create your own personal health profile and history.It will help you and create a base of knowledge for your children,their children, etc

3) a big failing of medicine = we wait till we are sick to have our blood tested and compare the results to "comparable demographics"

Led by ProPublica health reporter Charles Ornstein, a slew of doctors, health care experts, patient advocates and journalists tried to show Cuban the error of his ways. (You can read good summaries and perspectives on the exchange by Charles Ornstein, Dan Diamond, and Aaron Carroll.

The main problem with Cuban's idea is that it has absolutely no evidence to support it, and if widely accepted could lead to disastrous increases in spending with almost certainly no subsequent health benefit to individuals. The argument that it should only be done by those who can afford it won't hold water, because our health care system is almost completely incapable of taking cost into account once benefits have been widely promoted. More importantly, excessive testing inevitably leads to false positive results, turning healthy people into sick people and subjecting them to the whims and misfortunes of the health care system.

Cuban's main defense appears to be that the backlog of test records will help him and his physicians with medical care in the future, since new test results can be compared to his old results. This is an interesting concept but I'm afraid we are nowhere near the point in the vast majority of situations where this type of comparison would be helpful. For most doctors, this sort of avalanche of earlier tests would prove a huge distraction. And Cuban doesn't seem to realize that researchers have devoted an enormous amount of research trying to figure out how to interpret test results. It's extremely unlikely that an individual doctor or patient will be able to immediately improve on their work in the setting of an occasion where blood test results are actually needed. In any case, even if you accept the value of baseline tests, the idea of obtaining tests every 3 months would still require additional validation. This could well be a textbook definition of TMI.

Even Eric Topol, who is probably the most famous and vocal proponent of big data and patient empowerment, didn't endorse Cuban's recommendation, tweeting that the recommendation is "unfounded."
